I have always been told that it is possible to have a critical engine on a 737.
For example if there is a cross wind during take off. Which engine would be the least detrimental to lose in terms of handling the aircraft?
If the wind was from the left, losing the no. 1 engine would not be as bad as losing the no. 2. The yawing moment produced by the no. 2 engine would be counteracted a little by the crosswind, not compounded by it which would be the case if no. 2 engine was lost.
What do you think, was my instructor correct

I think he was!!!
